Originally, the Private Aichi Symbiosis Academy was a high school for upper-class girls. When it became co-ed, the females begged to be allowed to bring firearms to school out of fear. When it was enforced, the "Supreme Five Swords," a five-member vigilante corps-like group, was founded. After many generations, the five swords ultimately evolved into a group that corrected difficult pupils, and the school began enrolling such students proactively in order to fix them. After becoming involved in a large brawl, Nomura Fudou was sent to this school. What will he do when his two alternatives after enrolling are to be ejected from that school or to be rectified in the same way that the other male students there were...by being made to dress and behave?
